Patent number: 10507143Abstract: Excretion by a diaper wearer in a diaper is predicted by providing in or on the diaper on the wearer an excretion detector capable of detecting excretion by the diaper wearer and a motion sensor capable of detecting movements of the diaper wearer. The sensor continuously detects and at least temporarily records movements of the diaper wearer, and these detected movements are analyzed to determine movement patterns. Then, on detection of excretion by the detector, a movement pattern immediately preceding the detection of excretion is stored or flagged as a critical movement pattern. Thereafter each time movements matching the critical movement pattern are detected, a signal is sent to a user.Type: GrantFiled: April 14, 2017Date of Patent: December 17, 2019Assignee: REIFENHAEUSER GMBH & CO.
